Last year, the German Federal Agency for Disruptive Innovation (SPRIN-D) published the “Implementation Study on an Accelerator-Driven Neutron Source at the Site of a Former Nuclear Power Plant,” proposing an alternative waste management option. This type of radioactive waste management is often summarized under the broader term of Partitioning and Transmutation (P&T). The newly published INRAG Working Paper, "Scenario Analysis for Partitioning and Transmutation (P&T) in a Phase-Out Scenario," examines their assumptions more closely and reanalyzes possible scenarios.

Key findings are: 

The duration and scope of phase-out scenarios are heavily influenced by a small set of parameters. 

The amount of transuranium elements that need to be sent do final storage is intrinsically limited by cumulative losses and end-of-implementation reactor inventory. 

The framing in the SPRIN-D study does not constitute a national system description. A German-wide implementation necessarily requires a fleet of irradiation facilities and the associated fuel-cycle infrastructure, which could last for centuries.
